Battlestar Galactica may get the headlines, but Sci Fi Channel's slate of original movies has revived the cheesy 1950s B-movie genre and won strong ratings with such campy titles as Mansquito (half man, half mosquito, and buzzing back Saturday at 7 p.m. ET/PT) and Larva, in which mad cow disease leads a creature to emerge from hamburger meat.

Sci Fi will air 23 original films this year, second on cable only to the Hallmark Channel, and plans 28 for 2006. But its embrace of the drive-in movie was a happy accident. "We didn't set out to do this, but we started to see there was a trend," says the channel's general manager, David Howe.

"The ones that tended to pop are those with a fun element, that don't take themselves too seriously," Howe says. Those with "ludicrous creatures," simple plots and characters prove most successful. (Related story: Sci Fi universe colonizes brave new worlds)

Sci Fi's biggest son of drive-in movie was Alien Apocalypse, in which an astronaut doctor returns from space to find that Earth has been taken over by aliens. Three million viewers tuned in.

Many are filmed in offbeat locales such as Bulgaria and Romania and need little explanation. Take The Man with the Screaming Brain (due in September), which sells itself without noting that it concerns a murdered banker brought back to life with part of his brain replaced by that of Paco, a street hustler. The brain seeks vengeance on the pair's murderer.
